MF rod, also known as speed drill rod, features a male thread at one end and a female thread at the other end. It can directly connect to the shank adapter without the aid of a coupling sleeve, which eliminates the defect that the equal diameter thread connection is prone to vibration. The quick-change properties of male/female rods improve the overall drilling efficiency.
As an MF Rod manufacturer, we have two MF rod factories in China. Our MF drill rods are made of high-quality alloy steel and advanced thread manufacturing technology, and have excellent performance in wear resistance and flexibility. We offer speed drill rods with various threads, such as R23 MF drill rod, R32 MF drill rod, R38 MF rod, T35 MF rod, T38 MF drill rod, T45 MF rod, MF rod T51, GT60 MF drill rod, SR35 speed rod, etc.
